Examples of javax.enterprise.context.spi.Context

javax.enterprise.context.spi.Context
Every webbeans component has an associated context that are defined by the {@link NormalScope} annotation. Webbeans componentsthat are contained in the context are managed by the webbeans container.
Every context has a well-defined lifecycle. It means that in some time, context is active and some other time context may be passive. Moreover, each context is created and destroyed by the container according to the timing requirements. For example, request context is started by every http request and destroyed at the end of the http response. According to the current thread, active context is called an thread current context.

Context is responsible for creating and destroying the {@link Contextual} instances of thewebbeans components.
